What are metadata?

Metadata consists of information that characterizes your file. They answer background questions about who, how, when, and what. This gives your file multi-faceted documentation. https://0xacab.org/jvoisin/mat2/blob/master/README.md (09.2019)

The metadata of your file leak a lot of information about you. For example, cameras store file information about the time of a shot and which camera was used for it. Documents, such as PDF or Words, automatically add author or company information to the document. You don't want to publish all this information at all?

This is precisely the job of MAT2: getting rid, as much as possible, of metadata.
